In situ chemical vapour deposition-based graphene growth was designed with copper foil as a substrate and used to prepare copper matrix-graphene layered composites by spark plasma sintering. Mechanical properties and corrosion resistance of layered composites were greatly improved when sintered at 700°C and 25 kN for 10 min. Composite had 12% higher Vickers hardness and 30% higher tensile strength comparing with pure copper, respectively. The corrosion potential (Vcorr) of the layered composites shifted towards more positive values and the corrosion current (Icorr) was significantly lower than that of copper. Corrosion inhibition efficiency () was as high as 68.38% and 36.90%, and the corrosion rate (CR) was 0.047 and 0.093 mm year−1 for the parallel sample and vertical sample, respectively.
